Randomized trial of a video headset vs. a conventional video monitor during colonoscopy.



Head-mounted video displays recently became available for endoscopy. This study compared a video headset with a conventional monitor during colonoscopy.


Five endoscopists were randomized to headset or to monitor use during colonoscopy. They completed a questionnaire that assessed image quality, procedure characteristics, and comfort. Medication use and length of procedure were recorded.


A total of 96 colonoscopies were performed. Image quality and comfort were rated as poorer during headset use (p < 0.05). However, neck strain was significantly reduced with the headset. Medication use and total procedure time were similar. There was a trend toward increased time to cecum with the headset (9.8 vs. 8.0 minutes, p = 0.055).


In this randomized study, comparing a video headset and a conventional monitor for colonoscopy, image quality and comfort were inferior with the headset, although neck strain was improved. Further improvements in technology are needed before headsets can be considered an acceptable alternative to the conventional video monitor for GI endoscopy.
